Battle for Zendikar booster pack contains 15 cards per pack. Distribution is 1 rare or mythic rare, 3 uncommons, 10 commons, 1 land and a tip card. Battle for Zendikar will be the 68th Magic expansion, and the first in the Battle for Zendikar block. It will be released October 2, 2015. Battle for Zendikar is a large expansion, and the Battle for Zendikar block will be the first block with only 2 sets. (Lorwyn and Shadowmoor were considered a 4 block set)
The set contains 274 cards, which is 5 more than the current default for large sets, and includes randomly inserted premium versions of all cards in the set. The expansion symbol of the set is a broken hedron. The set features special full art basic lands similar to those that appeared in Zendikar.
Battle for Zendikar returns the storyline to Zendikar which previously has been featured in the Zendikar block. It is a plane of adventure, many treasures, and potent mana supplies. The plane is littered with large, floating polyhedron-shaped stones called Hedrons, that were created by Nahiri, the Kor Lithomancer. Together with Ugin and Sorin Markov she used them to trap the horrendous Eldrazi on the plane. Thousands of years later, the meeting of Sarkhan Vol, Chandra Nalaar and Jace Beleren in the Eye of Ugin chamber unintentionally loosened the bonds that kept the Eldrazi in torpor. The Eldrazi were finally released by the elf Nissa Revane, thinking that they would leave Zendikar far behind them. She was wrong. Two years after the initial destruction, at least Ulamog is still around.
Now, Gideon Jura takes the lead of a group of planeswalkers in facing the Eldrazi alongside the residents of Zendikar. Meanwhile, the trapped planeswalker-turned-demon Ob Nixilis is desperate for a way off of the plane. A pivotal moment in the storyline is the Slaughter at Sea Gate.
Battle for Zendikar will also feature Zendikar Expeditions. Expeditions is a set of 25 full art premium foils featuring the 10 fetch lands, 10 shock lands and the 5 duals in Battle for Zendikar. Their commonality will be slightly better than a mythic foil. In otherwords, 1 in 216 booster packs or 1 in 6 boxes. It is worth noting that Expeditions is reminiscent of the "Hidden Treasures" in Zendikar which ocurred with far less frequency at approximately 1 in 30 boxes.
